Abstract
Abstract A pair of upright post-like brake shoes extend down through apertures in a skateboard body member in slidable relation directly over a pair of the wheels, and the shoes are secured at their upper ends to a top cross plate arranged to be pushed downwardly by the skateboard operator to move the bottom ends of the shoes into engagement with the surface of the wheels for applying the brakes. A resilient retracting member holds the brake shoes normally above the wheels in a nonbraking position.
